The top institutions ranked by number of citations are NASA with 16,986,
and the Jet Propulsion Laboratory with 11,930 cites. These institutions are
the world's largest players in terms of spacecraft design, construction,
launch, and science operations. The University of Arizona is the
highest-placed research university. The French research council CNRS and
the Observatoire de Paris have a joint tally of 14,713.

For numbers of papers the running order is again NASA, JPL, Arizona, and
CNRS. Planetary exploration in the UK is largely down to Imperial College

Regarding Top 20 Scientists, Institutions, Journals, & Nations

Citation tables allow us to map compelling trends:

Are there particular nations or institutions that might be expected
to dominate research in the Topic area, and do the numbers bear out
these expectations, or are there surprises?

Who are the leading scientists and where are they located?

While these tables cannot offer a complete picture, the number of trends
and anomalies that can be spotlighted or connected across categories is
striking. The tables often lead to renewed perspectives to further explore
and validate.
